In the summer of 2001, an Italian journalist used an underwater robot to find the remains of a shipwreck off the coast of Sicily which had killed nearly 300 migrants from South Asia. At the time this was the worst disaster of its kind in the Mediterranean but the few survivors had been ignored by officials and dismissed as fantasists. The discovery of the so-called “Phantom Shipwreck” caused an outrage in Italy. Simon Watts talks to Italian journalist Giovanni Maria Bellu and the former Observer correspondent in Rome, John Hooper, who also investigated the tragedy.(Photo: The remains of the "Ghost Shipwreck" filmed off the Sicilian coast.

The inside story of how India secretly developed and exploded an atomic device in 1974. India called it a Peaceful Nuclear Explosion, though the experimental device was in effect a plutonium bomb. The test was seen as a triumph of Indian science and technology, but it led to the suspension of international nuclear co-operation with India, and spurred Pakistan to speed up development of its own nuclear bomb. Alex Last spoke to S.K Sikka, one of India's leading nuclear scientists, about his role in the secret project, code-named Smiling Buddha.Photo: A crater marks the site of the first Indian underground nuclear test conducted 18 May 1974 at Pokhran in the desert state of Rajasthan.
